Answer:

x = [tex]\frac{4+5y}{y+3}[/tex]

Step-by-step explanation:

Given

y = [tex]\frac{4-3x}{x-5}[/tex]

Multiply both sides by (x - 5)

y(x - 5) = 4 - 3x ← distribute left side

xy - 5y = 4 - 3x ( add 3x to both sides )

xy + 3x - 5y = 4 ( add 5y to both sides )

xy + 3x = 4 + 5y ← factor out x from each term on left side

x(y + 3) = 4 + 5y ← divide both sides by (x + 3)

x = [tex]\frac{4+5y}{y+3}[/tex]
